WINDOW-CLEANIN DEVICE.

Application filed August 3, 1920. Serial No. 400,955.

for cleaning both the inside and outside of a window-sash simultaneously and 'to the same extent.

Many devices for this purpose have been devised, but apparently without overcoming certain defects which appear to be adherent in substantially all of them, and it is with this in view that many details have been added, as hereinafter described, all of which are fully'disclosed in the following descrip tion when read in conjunction with the accompanying drawings, in which Fig. 1 is a front elevation of the preferred embodi ment of the device attached to a fragmentary portion of a window-sash and surrounding frame; Fig. 2 is a vertical section through the sash and frame showing the I improved cleaner in side elevation; and Fig.

3 is a section on the line 33 of Fig. 2.

Referring to the drawings, the device will be considered as being applied to any usual type of transparent window-glass 1, sur

rounded by a frame 2, positioned against the usual molding portion 3, and held in place by any suitable form of removable molding 4. The frame 2 is additionally provided with a transversely extending aperture 5, through which extends in rotatable engagement 3, rod 6, which at one end may if desired be provided with a handle-wheel 7 adjustably securedto said rod in any suitable manner as by means of a set-screw 8.

Secured to the opposite face of the said frame 2 are discs 9 rovided with apertures 10 in alignment wit the aperture 5 in the window-frame, and through which extends the rod 6. Thesediscs 9 are secured to the frame in any suitable manner as for instance by means of screws or transversely extending bolts 11, while said discs are provided with downwardly extending portions 12 provided upon their adjacent surfaces with enlarged bosses 13 extending centrally, which latter are apertures for receiving screws 14.

Surrounding the rod 6 and adjustably secureal thereto as by means of set-screws 15 are pinions 16, which are adapted to mesh with the gear-like portion 17 of a member revolvably secured to the outer face of the depending portion 12 of each of the plates 9 by means of the screws 14.

Extending thence downwardly from the gear portion 17 are integral angle bars 18, to which are removably secured in parallel relation rods 19, so that pieces of rubber, felt, or other material 20 can be removably yet firmly positioned between said lastnamed members 18 and 19, and when .positioned as shown in Figs. 2 and 3 the elements 20 will bear against the opposite surfaces of the transparent glass 1, and equally through out their longitudinal extent.

By grasping the knob 21, the bar. 18 to which it is directly secured can be oscillated throughout substantially 180 degrees around the screw let as a pivot, and by virtue of the gears 16 and 17 the rod 18 upon the opposite surface of the sash member 1 will be oscil lated to the exact same extent and simultaneously therewith.

i I using the hand-wheel 7, it is obviousl only necessary to make substantially a hal turn in either direction, or alternately in opposite directions with said wheel, and the rods 8, together with the cleaning members 20, will be oscillated as hereinbefore described with less angular motion of the arm of the operator.

Although'one form of the invention has been described, it isto be understood that various alterations might be made in'the details of construction without departing from v the scope of the appended claim.

' Having thus described our invention,

what we claim anddesire to protect by Letters Patent of the United States is:

A window-cleaning device, comprising a pair of plates having aligned apertures, said plates adapted to be positioned upon the opposite sides of a window frame, means to 'tion of each of said plates and meshing with In testimoliy Whe Q I 1,455,39e
